LTC6261 Typical Application


The LTC®6261/LTC6262/LTC6263 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, and rail-to-rail inputs and outputs. They are unity gain stable with capacitive loads up to 1nF. They feature 30MHz gain-bandwidth product, 7V/μs slew rate while consuming only 240μA of supply current per amplifier operating on supply voltages ranging from 1.8V to 5.25V. The combination of low supply current, low supply voltage, high gain bandwidth product and low noise makes the LTC6261 family unique among rail-to-rail input/output op amps with similar supply current. These operational amplifiers are ideal for low power and low noise applications.

For applications that require power-down, the LTC6261 in 2mm × 2mm DFN and LTC6262 in MSOP-10 offer shutdown which reduces the current consumption to 10μA maximum.

The LTC6261 family can be used as plug-in replacements for many commercially available op amps to reduce power and improve input/output range and performance.
